Touchpad vertical scroll registers as horizontal scroll only on YouTube videos

Firefox Web compatibility

I am using a Wacom tablet as a touchpad for my PC.

And its scrolling functionality works perfectly fine in every program except on YouTube, specifically when a video is playing.

All of a sudden, scrolling up or down now also registers as a horizontal scroll and skips the video timeline back and forth.

Tried disabling all I could think of related to gestures, horizontal scrolling, or smooth scrolling in the about:config page, but nothing worked.

Disabling the vertical scroll action in the tablet's software does disable vertical scrolling in Firefox as well, as expected. So, changes are getting applied. However, not so for left/right gestures, disabling those in the software had no impact whatsoever in Firefox (on YouTube videos).

Finally, this issue does not occur on Chrome at all. Chrome can handle vertical scrolling on YouTube videos just fine with no need to disable anything.

So, hardware wise, everything is working fine.

Is there any solution to this?

I am perfectly fine disabling any horizontal scrolling gesture whatsoever if that turns out to be the solution.

Thank you!
